M&S says

For that perfect summer look, this ladies’ swimsuit uses Secret Slimming™ technology to give you a great figure and silhouette both on and off the beach, along with the bonus of our Stay New™ Chlorine Resist finish to keep it looking pristine for a long time to come. Our non-wired swimsuit has a quirky look, with a striped style in bright tones, a sleek, boastful design with plenty of charm.
